YOUR QUESTION. A CLEARER NEXT STEP.
Emotional Milestones for a 9-to-12-Month-Old
By 9–12 months, most babies show clear attachment to favourite people, look to you for reassurance, share feelings by pointing and reaching, and may show shyness with strangers. Babies reach these at their own pace; a gentle check helps if your baby rarely shares smiles, doesn't respond to their name, or loses a skill by 12 months.
In this answer 5 sections
Between nine months and a year, your baby's heart is learning the most human lesson of all — that love comes back. Every wave, every reach for you, every shy glance at a stranger is emotional development in motion.
In short
Between 9 and 12 months, most babies show a clear, warm bond with their favourite people, look to you for reassurance, and may show some shyness or wariness around strangers. They begin to share feelings — pointing to show you things, raising arms to be picked up, and checking your face before trying something new. These are wonderful, normal signs, and babies reach them at their own pace.
Emotional milestones to enjoy and watch for
Connection and comfort
- Shows clear attachment — reaches for you, calms when held by a familiar person
- May show separation upset when you leave, and joy when you return
- Looks to your face for reassurance before doing something new (social referencing)
Sharing feelings
- Smiles, laughs and "talks" back in happy exchanges
- Points or holds up objects to show you — sharing interest, not just wanting
- Raises arms to be picked up; may play simple games like peek-a-boo with delight
Early self-expression
- Shows a range of feelings — happiness, frustration, curiosity, surprise
- May show some shyness or wariness around new people (this is healthy)
- Begins to show preferences for certain toys, people and routines
Remember — a calmer, more cautious baby and a bubbly, outgoing baby can both be developing beautifully. Temperament varies, and the milestones are a guide, not a test.
When a gentle check helps
Most variation is completely normal. It's worth a friendly developmental check if, by around 12 months, your baby rarely makes eye contact, doesn't respond to their own name, shows little interest in sharing smiles or sounds with you, or has lost a skill they once had. None of these means something is wrong — they simply mean a quick look is wise, and early support is always gentle and effective.

CONNECT THE ANSWER TO YOUR CHILD’S DAY
Something to notice. Something to discuss.
What to notice
By around 12 months: rarely makes eye contact, doesn't respond to their name, shows little interest in sharing smiles or sounds, or has lost a skill once present. These don't mean something is wrong — they simply mean a quick, friendly developmental check is wise.
In everyday life
Play peek-a-boo and name-and-point games daily — pause and wait for your baby to react. These back-and-forth moments are how emotional connection grows.

Bring your questions to a first visitQuestions families ask
Is it normal for my 9-month-old to cry when I leave the room?
Yes — separation upset usually appears around this age and is a healthy sign of attachment. It shows your baby knows and loves their special people. It tends to ease with reassuring, predictable goodbyes and warm reunions.
My baby is shy around strangers. Should I worry?
Not at all. Some wariness around new faces between 9 and 12 months is completely normal and shows your baby can tell familiar people from unfamiliar ones. Calmer, more cautious babies are developing just as well as outgoing ones.
When should I ask for a developmental check?
A gentle check is wise if, by around 12 months, your baby rarely makes eye contact, doesn't respond to their name, shows little interest in sharing smiles or sounds, or has lost a skill they once had. This isn't a diagnosis — just a friendly, early look.
